Magnetoelectric encoder is a new type of Angle velocity distance or displacement measuring device. Magnetoelectric encoder advantages not easily affected by dust and dewing magnetoelectric encoder; Its simple and compact structure, non-contact, long life, high and low temperature resistance, resistance to vibration, fast response speed. Cost is low. Magnetoelectric encoder applications magnetoelectric encoder used in robot, automatic production lines, automatic assembly machine, elevator, textile machinery, sewing machinery, packaging and printing machinery, CNC machine tools, mapper and Angle measuring instrument, etc. Can also be in PLC application as the high speed signal input element, make PLC more quickly and accurately implement the closed-loop control. Working principle of the magnetoelectric encoder magnetoelectric encoder principle is to use magnetic resistance or element to change to measure the Angle or displacement values of magnetic materials, magnetic materials Angle or displacement change will cause a certain resistance or voltage changes, through single chip microcomputer or analog signal output pulse signal after processing, to achieve the purpose of measuring. Concentric code, starting from the center of the magnetic encoder encoder, extending outward until the encoder outside, each layer of code that is a times more than its inner partition. The first layer is only a light sectors and an opaque sector, is located on the second floor of the center has two transmission sector and opaque sector; And the third layer code of pervious to light sectors and opaque sector will each have four. Embedded sensing head volume is small, be applicable to the small installation space, and USES the high level of protection design, can use in the bad environment, in industrial situations can avoid the sensitivity of the general optical environment pollution, increase the system stability. Magnetoelectric encoder by A central shaft of light code disc, on which there are circular and dark scribed line, have read photoelectric emission and receiving devices, obtain four groups of sine wave signal into A, B, C, D, each sine wave phase difference 90 degrees, will reverse, C, D signal superimposed on A, B two phase, can strengthen stability of signal; Every turn output another Z pulse to represent a zero reference. Because of A, B two phase difference of 90 degrees, but only through A phase in the former or B phase in the former, with forward and inversion of magnetic encoder, through the zero pulse, can obtain the zero reference. Shanghai electronics factory specializing in the production of magnetoelectric encoder, research and development of this magnetoelectric encoder dimension and height can be customized according to customer requirements, electronic advanced production testing equipment, product quality and reliable is the choice of magnetoelectric encoder supplier quality!
